It has a fairly straight grain, sometimes irregular, and a course uneven texture.

Tips: Although variable, Teak can be worked with moderate ease with both hand and machine tools. There is moderate to severe dulling of cutting edge, but if these are kept sharpened the wood finishes well. It takes nails and screws fairly well and glues satisfactory on freshly machined and sanded surfaces. Because of the oily nature of the Teak, some form of degreasing/washing is required when gluing previously exposed surfaces. It can be varnished or polished satisfactorily.
